Answer:
d). X-rays
Explanation:
X -rays are also called photons. They are a packet of electro magnetic radiation. X rays originate from the shell of the electron. X rays are highly penetrating, and have a shorter wavelength than alpha particles and the beta particles. They are similar to the gamma rays which are also has a high penetrating power and easily pass through the human body.
Thus X rays can penetrate a skin tissue upto 2 cm thickness.
Answer:
D. X-Rays
Explanation:
Alpha and beta particles are actually particulate radiation. X and Gamma rays are electromagnetic radiation.
Among the options, beta particles and X-Rays are the ones that can penetrate skin, but only X-Rays can go 2 cm deeper.
Actually, beta particles or beta radiation in the tissue can penetrate just a few milimeters, but X-Rays can penetrate many centimeters. That's why X-Rays are used to examine bones, it's too deep to use beta radiation.
Therefore, the right answer is D.
